About our AHU cleaning in Merstone

If the units serving a building in Merstone have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. The work covers heating and cooling coils, internal panels and supply and extract fans, and people most often call us about odours coming through the supply air and coils clogged with dust and debris.

In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.

A written report with photos follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Your questions about AHU cleaning in Merstone

Do you offer AHU cleaning in Merstone?

Yes, we work in Merstone and the places around it. Just call us on 0345 646 2711 or drop us a line with a few details of the site.

Can the work in Merstone be done at night or at weekends?

Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Merstone needn’t be disturbed. When you ring 0345 646 2711 or send us an email, mention when the site is quiet.

Can you set up regular visits?

Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.

What do you do to protect the area?

By covering it before any work starts. We keep the work contained and leave the area clean.

Do you clean the ductwork as well?

Yes, supply and extract ducts, grilles and diffusers. We’ll tell you after the survey whether the ducts need it.

Does the AHU have to be shut down for cleaning?

Yes, for the time we’re working on it. We can work evenings, overnight or at weekends so the building isn’t left without ventilation when it’s busy.

Do you work with multi-site operators?

Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.

How much does AHU cleaning cost in Merstone?

Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we’ll typically reply within one working day.

How we price AHU cleaning

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • How many systems or sites are involved
  • How easy every part is to reach
  • One-off work versus a regular cycle
  • Any permits to work or inductions

A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before work begins.

What to send for a quote

You do not need the technical terms. Just send:

  • When the site is open and when it’s quiet
  • Detail shots of panels, filters and grilles
  • Photos showing the whole system and its surroundings
  • Any symptoms, from odd noises to smells or leaks

There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, give us a ring on 0345 646 2711 or email us.

What the work involves, part by part

Rooftop and plant room units

Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.

Heating and cooling coils

A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.

Why act early in Merstone

A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. With notice, the visit to Merstone can be fitted around your bookings and events.

Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, give us a ring on 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.

What you get with us

  • Survey first, then a fixed quote
  • Accredited under CHAS and SafeContractor, with ISO 9001
  • Photo reports with every job
  • Fixed quotes from a survey or pictures

Common problems we fix in Merstone

Air handling units are usually tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.

Signs it’s time to call us include:

  • Dust built up on fan impellers
  • Rooms that smell stuffy when the system runs
  • Leaves and litter drawn into the unit
  • Blocked condensate drains and slimy trays

Hospitals such as Whitecroft Hospital (about 2.2 miles west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Merstone are no different.

Our hiring checklist

How it works

Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. The timing of a visit to Merstone is set by you, and the travel is our side of the planning.

  1. The survey covers the unit, its access and how it can be shut down.
  2. We sheet the area and the unit is isolated.
  3. Dirt and debris are removed from each section.
  4. We clean the coils and clear the tray and drain.
  5. We close every panel, hand the unit back and send the report and certificate.

Getting ready for the visit

  • Clear the space around the work
  • Tell us about site rules, permits or sign-in
  • Find the previous report, if there is one

Getting a quote

Getting a quote doesn’t take long. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

What staff can safely do

Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.

Looking after it afterwards

So the system stays in good health:

  • Keep filter changes on time and recorded
  • File each AHU report in the maintenance log
  • Note any water around the unit or leaks below it
  • Do not store bins or materials near the intake

Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.

Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
